RT Journal T1 LAboratory manual of the massachusetts general hospital. JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1929 FD January 19 VO 92 IS 3 SP 256 OP 256 DO 10.1001/jama.1929.02700290066033 UL http://dx.doi.org/10.1001/jama.1929.02700290066033 AB This manual, prepared by interns in the Massachusetts General Hospital, was intended as a pocket outline of the routine laboratory work done by them. It was found to be of interest to a wider group and the first edition was soon exhausted. The material has now been revised and extended. The book is still a pocket edition with flexible cover. The last page is numbered 101; the scientific material starts on page 17. There is a chapter on the examination of urine, blood, feces, sputum, gastric contents, spinal fluid, how to collect specimens, and special diagnostic procedures, including the newer laboratory procedures of clinical value. This material as well as the arrangement is good.
